    some actual width data for Clement XPlor tires on my rims

    MSO 40mm on open pro rims 14.5mm inner width @ 30psi
    37.5 at bumps
    35.4 at sidewall
    Hgt 35
    On Kinlin 279 rims (17mm inner)
    38.4
    36.7
    Hgt 36

    USH 35mm On open pro
    31.8
    on Kinlin 279 rims at 50psi
    32.5 sidewall
    31 hgt

    Tires are fairly new, under 200 miles.

    So yes, wider rims makes your tires a little wider.

    Thanks for sharing...looks like I could put the MSO 40's on my bike without any tire clearance issues. Out of curiousity, have you run the MSO 40s much on your 14.5mm rims? I'd be interested to know if you encountered any stability issues...according to all of the charts, that tire is too big for that rim (but I'm considering doing something similar in the near future).

    Darn good question. Usually you would want at least a 17mm rim for a 40mm tire.

    That's the impression I was under. Then again, the consensus also seems to be that the charts are a little conservative...I get the feeling a lot of people go over without a second thought.

    I did ride them a little on the open pro rims, probably less than 50 miles. The tires stayed on the rims just fine, I was running low pressure, probably 25-30, and riding mostly offroad

    oh, I see, you mounted them just out of curiosity and to measure the inflated dimensions... and now you're riding them on the wider rims.

    that makes sense. FWIW, my DT Swiss R24 Spline are 17mm inner width, and DT's tire chart shows 23-35 mm being OK. I put WTB Nano 40s on there anyway, and they're rounded, but don't burp air at the pressures I run.

    I'm getting a width of 39.3mm at the sidewall and 39.7mm at the knobs with the 120 tpi MSO mounted on Velocity Dyad rims. These tires have only been inflated for 48 hours, and I expect them to grow a few a small amount over the next few weeks. The Dyad is 24mm wide, Velocity does not publish the inside width on its website.
